Analysis :: Tabular - Filter / Search For A Specific Measure Value?

One of my models has order data, cost per order/invoice ID and then dimensions on Fiscal Year, category, etc...the usual.

A user wanted to search it for an exact order amount.  (They knew for example that one of our accounts was not balancing by single order worth $746.13 and assumed it must be an order that was placed but never marked shipped that slipped through the cracks).

Now, in the model I have "order amount" as a field and then a measure that sums that.

I could expose that "order amount" field as a label and let them filter on it in Excel (and that works).

However, I haven't had any luck filtering on the actual measure "Total Order Amount".  Such as OrderID-> View Filter -> "Total Order Amount" equals 746.13.

I assume this is due to a few things:

Measure calculates at different levels so filtering on a measure is difficult as you would have to place all the "slicers" and set them first before the measure would "exist" at a level where it could be $746.13.  Orders by year would have $746.13 as part of it's year sum, but wouldn't exist as a stand alone line item orders by year 2015 might be 2 million. 

Orders by category might exist at 500,000, 8,000, 15,146.36, etc... but not $746.13.

So I would need OrderID on there as a column so the measure could return at the value of $746.13 for one row for it to match the filter?

Basically:
1. Why it can't really filter on a measure?
2. Is there a better way to accomplish this other than exposing the actual column in the fact table "order amount" as it feels like that could cause all kinds of confusion if other users try to slice/filter on that not realizing exactly what it is meant to be?
